It's not clear yet who's in and who's out for Sunday's London matchup against the Bengals, but there were some positive signs at Redskins practice.

ASHBURN -- Tight end Jordan Reed claims he's symptom free after missing two games with a concussion. Left tackle Trent Williams vows to play against Cincinnati Sunday in London after needing help just moving around in the final moments of the Week 7 loss at Detroit. Cornerback Josh Norman, like Reed, is recovering from a concussion and was a limited participant at Wednesday's practice.

Those three are the headliners when it comes to injuries for the Washington Redskins. They are hardly alone.

Head coach Jay Gruden mentioned the names of 11 players who missed some or all of practice. Other than that notable trio, the most interesting of those names, running back Matt Jones, who didn't participate due to a knee injury that was not mentioned after the 20-17 loss.

"You know, he just came in I guess today, had some soreness laterally, had some pain cutting," Gruden said of Washington's leading rusher. "He was OK running straight ahead...we kept him out today."

With the team heading to London Thursday night, a call will be made on Reed and Norman earlier than normal. "Thursday they are going to go to the independent doctor and if they’re cleared, they’ll go on the trip," Gruden said. "If they’re not cleared, if we’re having still some pain and setbacks, at that point we’ll make that decision to probably leave them back.”

Reed believes he's in position to return despite recovering from his sixth known concussion.

Williams vowed to play after an MRI Monday revealed know significant injury. That doesn't mean he's close to healthy. The Pro Bowler said he'd face the Bengals even if just 80 percent while admitting he's not even 80 percent at this moment.

Gruden considered Norman's presence Wednesday "a good first step" but he wouldn't offer a prediction for Sunday especially with his specific injury. There's no doubt the coach will breathe easier if the corner is available to battle Cincinnati's star receiver, A.J. Green.

“Well, Josh is best corner in the league, so yeah. Yeah, no doubt about it," Gruden said. "One of the best, I don’t want to start an argument there, whatever you want to say. Anytime your best player is not going to go, it has a concern, but when he does go, you have a comfort level. That’s why we signed him for guys like A.J. Green and that matter, but either way we still have to strap it up and play. If he doesn’t go we feel good about [Bashaud] Breeland, we feel good about [Quinton] Dunbar and [Greg] Toler, like I said. So we’ve got a great competitive group. They show no fear back there and they’re going to compete.”
